The troubles keep mounting for Tracy Anderson. The celebrity trainer, who has worked with Gwyneth Paltrow and Molly Simms, has been dropped by Madonna, her most notable client, a source close to the singer tells Page Six.

Madonna herself confirmed she was no longer training with Anderson during an interview on Ryan Seacrest‘s KIIS-FM radio show last week. Asked by Seacrest whether she had “dropped” Anderson, Madonna simply laughed.

According to our source, “Madonna had grown tired of the baggage that Tracy always seemed to be carrying with her. Tracy had grown to be more of a distraction than anything else.”

Also an issue were photos of Madonna that circulated in July that showed her arms to be grotesquely over-muscular. When Anderson was asked about the pictures on the CBS “Early Show,” she laughed and called Madonna her “most devoted client.”

Things between the Material Girl and Anderson might also have gotten personal. We reported last month that Philippe van den Bossche, the former head of Madonna’s Raising Malawi charity, had quit his post in Los Angeles to move to New York to date Anderson. Van den Bossche was quoted as saying that Madonna was “happy” about his relationship with the trainer. But Madge was said to be disappointed when Anderson wouldn’t travel with her on the final leg of her recent European tour until the very end so she could be with Van den Bossche.

Anderson has been in the news before — in December 2006, she was briefly hauled off to jail for failing to pay a $271.32 bill to a chimney sweep. Reached for comment, Anderson’s publicist says, “This is not true. After working together for three years, Tracy and Madonna mutually parted ways because Tracy wanted to look after her son.”
